What is Brachial Plexus?
The brachial plexus is a complex network of nerves extending from the neck into each arm. This nerve network controls movement and sensation in the shoulder, arm, wrist, hand and fingers.
Brachial plexus palsy, also commonly referred to as Erb's palsy, affects the nerves passing from the neck to the arm. These are the nerves that trigger movement from the shoulder down to the fingers.
Depending on the type of brachial plexus palsy, symptoms appear in the shoulder, elbow and/or hand and fingers. These symptoms include loss of feeling, loss of muscle control, and limited or no range of motion.
The most common cause of brachial plexus palsy is a stretching, compressing or tearing of the nerves which may result in scar formation.
Although some brachial plexus palsies heal on their own, others may result in a lifelong disability if not treated promptly.
